RX-77-2 Guncannon (RX-77-2 ガンキャノン) is a Mobile Suit designed by the Earth Federation, a part of the same RX series as Gundam. To improve the mobility of their common Guntanks, the Federation engineers strove to design a walking Mobile Suit with hopes to easily maneuver over jagged terrain. The early models for the prototype Mobile Suit were stolen by Zeon to create Zakus, so Guncannon is actually the second of its particular model. Three Guncannons were manufactured and were sent for testing at Side 7. During the Zeon invasion of the space colony, two models were destroyed. However, the final Guncannon was stationed on White Base and became one of the main defenders of the space ship during the One Year War.

Compared to its cousin, Gundam, Guncannon is a bulkier Mobile Suit with similar armor plating and construction. Its frame doesn't allow for quick movements, however, so its significantly slower than its counterpart. Guncannon's armor isn't as resilient as Gundam's structure since it's made from malleable material. It has no reliable close ranged weaponry to defend itself so the pilot is in extreme danger if foes successfully dodge or block Guncannon's attacks. To counter these setbacks, Guncannon is equipped with various mid-ranged artillery to keep foes at bay.
